# Lottery

![](/files/-McCSEzlahwmuLCRTtH_)

## **Specifics:**

* Price per ticket: 10 BULL&#x20;
* Limits per user: There is no maximum limit but only 50 can be purchased at a time via the User Interface.&#x20;
* Each ticket will give the user a random combination of 4 digits, with each digit ranging from 1 to 14. For example: "1-9-3-14".

## **How to win:**

To win the lottery jackpot (50% of the entire lottery pool), users need to match all 4 numbers on their ticket in the **exact same order** as the 4 winning numbers.

If you don’t match all 4, no need to worry. As long as you match 2 or more numbers in the correct order, you are guaranteed to win a prize.

### **Winning ratio:**

* Match all 4 numbers in the exact order = win 50% of the pot (or split the pot if more than 1 winner).&#x20;
* Match 3 numbers in the exact order = win or split 20% of the pot.
* Match 2 numbers in the exact order = win or split 10% of the pot.
* 15% of the pot saved for the next Lottery.
* 5% as a protocol fee.

Please note - in the event that no participants were able to match 2, 3 or 4 numbers, the pot will be carried over to the next Lottery minus the protocol fee.

For example, if the final 4 winning numbers are “1-9-3-2”:

* “2-3-9-1” = match 0
* **“1-9-3-2” = match all 4**
* “1-9-2-2” = match 3
* “2-3-3-2” = match 2
* “1-2-1-2” = match 2

## **Lottery phases:**

Each full lottery session is completed every 12 hours (2 per day), with the timings for each as below:

3 AM  - 2 PM (UTC)

The next lottery will start in 1 hour!

## **How are ticket numbers drawn?**

The lottery aims to be completely random. Even though the ticket numbers given out are determined by a front-end logic, there is an extremely low chance that anyone is able to determine the 4 winning numbers ahead of time.

* The 1st lottery number will be determined based on the %10 remainder of a hash encoded by the blockhash and the number of participating users at the entry deadline.
* The 2nd lottery number will be determined based on the %10 remainder of a hash encoded by the blockhash and the total pooled bull balance at the entry deadline.
* The 3rd lottery number will be determined based on the %10 remainder of a hash encoded by the blockhash and the timestamp of the last lottery participant at the entry deadline.
* The 4th lottery number will be determined based on the %10 remainder of a hash encoded by the blockhash and the block difficulty at the entry deadline.
